Specification of Letters Patent.

Patented Aug. 8, 1911.

Application filed August 4, 1910. vSerial No. 575,440.

To all whom it may concern:

Be it known that I, JAMES; C. Lonen, a citizen of the United States,residing` at Vilmington, in the county of New I-Ianover and State ofNorth Carolina, have invented certain new and useful Improvements inLocks, of which the following is a specification.

My invention relates to locks and particularly to locks of the gravitytype.

An important object of this invention is to provide a gravitylock,-which is formed of few and simple parts, and which parts cannot beactuated by an improper key.

Other objects and advantages `of my invention will be apparent in thecourse of the following description.

In the accompanyingdrawings, forming a part of this specification, andin which like numerals are employed to-designate like partsthroughoutthe same, Figure 1 is a side view of my lock, one side of thecasing being removed, Fig. 2 is a vertical crosssectional view taken online 2--2 of Fig. 1, Fig. 3 is a side view ofthe key for moving thetumbler, Fig. 4 is an enlarged detail sectional view through the lockingmechanism for the bolts, taken on line 4-4 of Fig. 1, Fig. 5 is a sideview of the key to coperate with said locking mechanism,:Fig. 6 is aside View of a modified form of lock and showing one side `of the casingremoved, Fig. 7 is a vertical cross-sectional view taken on line 7-7 ofFig. 6, Fig. 8 is a side view of a key to coperate with the form of lockshown in Figs. 6 and 7, Fig. 9 is a view similar to Fig. 7, and showingthe lock provided with an extended spindle for carrying a handle, andFig. 10 is a side view of a` key to be used in connection with the formof lock shown in Fig. 9.

The form of lock shown in Figs. 1 to 5, inclusive, is particularly welladapted for use upon safety deposit boxes or vaults. This lock comprisesa preferably rectangular casing 1, within which are mounted spaced disks2 and 3. Disposed between these disks and eccentrically arranged withrelation to the same is a tumbler or weight 4 having rigid connectionwith said disks by means of pins 5 or the like. The disks 2 and 3 arepivotally mounted upon a spindie 6 having reduced ends 7, which arerotatably mounted `within suitable openings formed through the sides ofthe casing 1. This spindle is provided withan aXial opening 8 forreceiving a suitable key 9 carrying teeth 10. A ward 11 is disposed nearthe spindle 6, as shown in Fig. 1 and has rigid connection with thecasing 1 by means of a pin 12, which is disposed within a curved slot 13formed through the disk 3. This Ward is stationary `with relation to thecasing 1 and is provided with suitable curved openings or slots 14. Fromthe construction of the above referred to parts, it is obvious that thekey 9 may be inserted within the spindle 6 and rotated so that its teeth10 engage the tumbler 4 to oscillate the same. If a `key is employedhaving teeth notarranged in the same manner as the teeth on the key 9,such key cannot be rotated 4past the ward 11 and therefore could notaetuate the tumbler. It is to be understood that the form of key showninFig. 3

vmay be altered, provided that the ward 11 is correspondingly altered tocooperate therewith.

The casing 1 is provided near its corners with tracks or guides 15between which are slidably mounted bolts 16. As shown in Fig. l, thereare four of these bolts, which have their innerends pivotally connectedwith arms 17, as shown at 18, said arms having their inner ends disposedbetween and pivotally connected with the disks 2 and 3, as shown at 19.Certain of the bolts 16 are provided with cut-out portions 2O forreceiving the free end of a pivoted tumbler or Weight 21. Each of theweights 21 has a ward 22 arranged near the same, as shown, havingsuitable openings 23 formed therethrough to receive teeth 24 of a key25. These tumblers 21, together with their wards and keys, constitutelocking mechanism for the bolts 16. I wish it understood that I mayequip one or all of the bolts with the locking mechanism above referredto, and that the locking mechanism for each bolt may preferably employ adifferent key. It will thus be seen that if the four bolts 16 wereprovided with locking mechanisms, and each mechanism was unlocked by adifferent key, counting the key to actuate the tumbler 4, it would takefive different keys to actuate the lock so that the door to which thesame is secured could be opened.

In the form of lock as shown in Figs. 6 to 8, inclusive, a preferablyrectangular casing 2G is provided, having tracks or guides 27, betweenwhich is slidably mounted a bolt 28. This bolt has pivotal connection,as

shown at 29, with an arm `30, the inner end of which is pivotallyconnected with a tumbler or weight 31, as shown at 32. This tumbler 3lis preferably triangular and is pivotally mounted upon a spindle 32a,having reduced cylindrical ends 33-which are rotatably mounted withinsuitable openings formed through the sides of the casing 26. The spindle32EL is provided with .in axial opening 34 for receiving a key 35 havingteeth 36. Arranged near and below the spindle 32a is a stationary ward37 which is rigidly connected with the casing 26. This ward is providedwith openings or grooves 38 to allow of the passage of the teeth 36,whereby said teeth may engage the tumbler 31 for oscillating the same.It is obvious that the ward 37 will prevent the use o'l' an improperkey. The downward movement othe tumbler 31 and accordingly the outwardthrow of the bolt 28, may be regulated by the proper manipulation of avscrew 39 tapped through the casing 26.

The lock shown in Fig. 9 is of the same construction as that shown inFigs. 6 and 7, except that the spindle 32a is dispensed with and thetumbler 31 is pivotally mounted upon a long spindle 40 which extendsoutwardly of the casing 26, as shown. ThisV spindle is rotatably mountedwithin openings formed through the casing 26. This spindle 40 isprovided near its ends with a plurality of annular grooves 41 to receivea pawl 42 carried upon the tubular body portion ot a handle 43. Thespindle 40 is provided with an axial opening 44 for receiving a key 45having teeth 46. The handle 43 is also provided with a suitable openingfor the reception of the key 45. The key 45 is adapted to fit snuglywithin the handle 43 and be held therein by a pin (not shown) which isto be inserted through the opening 47. The pawl 42 is held in its properposition by a spring 48 suitably secured to the tubular body portion ofthe handle 43. Although T have shown only one handle arranged upon thespindle 40, it is to be understood that a corresponding handle should bearranged upon each end of the same.V A ward 49 is disposed near thespindle 40 for coperationv with the key 45 to prevent the employment ofan improper key.

Tn the operation of the lock shown in Figs. 1 to 5 inclusive, each ofthe bolts 16 are first released so that they are :tree to move, and thenthe disks 2 and 3 are rotated by the key 9. This rotation of the diskdraws the bolts 16 wi-thin the casing 1. It is obvious that when the key9 is released the tumbler 4 will return the bolts 16 to their outerpositions.

Tt is thought that t-he operation of the lock disclosed in Figs. 6 to 10inclusive is obvious, and such operation will not be stated.

T wish it understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatcertain changes in the shape, size and arrangement of parts may beresorted to without departing 'from the spirit of my invention or thescope of the subjoined claims.

Having fully described my invention, I claim l. ln a lock of thecharacter described, a casing, a spindle pivotally mounted within saidcasing, a tumbler pivotally mounted upon said spindle, a bolt havingslidable engagement with the casing, means connecting said tumbler andbolt, said spindle being provided with an axial opening, and a key forinsertion within said axial opening, having a portion extending beyondthe periphery of the spindle to engage the tumbler for effecting amovement of the same.
